This is possibly a couple of years out of date now but…
I had a pir of Oro Biancos on my Soda. Light, powerful, really nice feel. Fantatsic in the dry. In the wet? Pad life could be measured in a couple of hours. That was trying a variety of makers.
I also bought a pair of old style Ones. Other than being light, I never, ever managed to make them work properly, consistently. Constant rebleeds, unreliable lever feel, and they never felt as strong as the Oros, even with bigger rotors. Pad life in the wet was also appalling – although I generally could get 2 rides out a set rather than one. Getting hold of spare pads was also an issue, although that has improved.
I’ve now moved on to Hopes, and am very happy – heavier, but they just work, and I’m getting a minimum of 6 months per set of pads. I understand the R1 style levers have improved things, but I can’t be arsed with faffing around any more finding out.
